How does a stop-loss work?

Stoploss: Definition, how it works, types, examples, mistakes to avoid. A stop-loss is an advance order placed with a broker to liquidate a position at a predefined price level. Stop-losses are of three main types. They are fixed stop-losses where the stop price does not change, trailing stop-losses where the stop price moves as the market moves in favor of the trader and guaranteed stop-losses offered by some brokers which guarantee the fill even in volatile market conditions. The main advantage of using a stop-loss is that it allows traders to cut their losses within a defined risk level if the market moves against their position. However, one limitation is that during periods of high volatility, there is a possibility that the stop-loss may be triggered due to temporary price spikes. A trailing stop-loss helps lock in profits while giving the market room to move in the favorable direction. Fixed stop-losses are easy to implement but may not protect against fluctuations in the underlying security. Guaranteed stops provide extra security for traders but involve higher brokerage costs compared to regular stops. The correct selection and placement of stop-losses is crucial for risk management in trading.

What are stop-loss orders?

A stoploss order is a type of order placed by a trader to limit potential losses on a position. Stop-loss orders work by automatically closing the position when the price falls to a predetermined stop-loss level. Setting a stop-loss allows traders to control their risk exposure by limiting the maximum loss they are willing to accept on a trade. The stop-loss order is triggered and the position is closed before losses exceed the stop price as share prices begin to move against the trader’s position. Stop losses are often used by traders who want to protect profits made in the past or limit the downside when shorting stocks. Although stoploss orders do not guarantee execution at the exact stop price in volatile markets, they remain an important risk management tool.

How a stoploss order works

Stoploss orders work by allowing investors to limit their potential losses on a trade. It is an order placed with a broker to sell a security when it reaches a certain price, known as the stop price. The stop-loss order becomes a market order to sell when the stop price is reached. This helps investors limit their downside if the price of a stock falls after they buy it. The stop-loss order is sent as a market order that will be executed at the next available market price when the stop price is triggered. Stoploss orders do not guarantee execution at the stop price, as the market price may go below the specified stop price. Using stop-loss orders helps traders and investors to define and limit their risk on trades in case the market moves against them.

What types of stoploss are there?

The types of stoploss orders include firm, trailing stop loss and guaranteed stoploss.

1. fixed stoploss

Fixed stoploss orders set a fixed stop price below the current market price of a security. Investors use them to limit potential losses on a long trade if the market price falls. For example, an investor buys a stock for $350 and sets a fixed stoploss at $315, 10% below the purchase price. This stoploss triggers a market order to sell the shares if the market price falls to $315. This closes the position and locks in a maximum loss of SEK 35 per share. Fixed stoplosses remain static and do not follow the market price like other stoploss types. The main advantage is that investors know the exact price at which their position will close. A disadvantage is that if the price falls quickly, the stoploss sometimes triggers significantly below the defined stop price. A stop-loss does not guarantee execution at the stop price.

2. trailing stop-loss

Trailing stoploss, or Trailing stop-loss orders follow the market price of a security as it rises and update the stop price accordingly. Investors use them to lock in profits on a long trade while protecting the downside. For example, an investor buys a stock for $350 and sets a 20 percent trailing stop-loss. The stop price adjusts to $336, which is 20% below $420 if the price rises to $420. The stop-loss triggers a market sell order if the stock then falls to SEK 336. The advantage is that investors ride a stock higher without giving back all the gains if it falls. Unlike fixed stoplosses, trailing stoplosses follow the stock price’s upward trend. One disadvantage is that volatility triggers stoplosses prematurely if the price swings back and forth. Trailing stops are best for stocks trending higher compared to range-bound securities. They allow investors to let profits run while having an order in place to automatically sell if the trend reverses.

3. guaranteed stoploss

Guaranteed stoploss orders provide certainty that if triggered, a trade will be executed at the exact stop price set by the investor. Brokers guarantee that stoplosses will be filled at the specified price regardless of market gaps or slippage. Investors use them for risk management to definitely limit potential losses on a trade. For example, an investor who longs for shares at ₹350 sets a guaranteed stoploss of ₹315. No matter how fast the price drops or market conditions, their trade will close at $3.50 if the stop is reached. A main benefit is the elimination of slippage risk that affects regular stoploss orders in volatile markets. However, the safety comes at a premium, as brokers charge higher fees for guaranteed stoploss orders. They require the broker to potentially take the other side of the trade when the stop is triggered. Guaranteed stops provide downside protection at a defined risk, allowing investors to size positions appropriately. Although expensive, they give traders peace of mind that their loss will be limited to the predetermined amount. The main stoploss orders – fixed, trailing and guaranteed – each have unique uses in controlling potential losses. Fixed stops lock in an exit price while trailing stops follow the market higher. Guaranteed stops provide certainty of execution at the predefined stop price. By understanding the differences between stoploss order types, market participants can effectively implement strategies to limit downside based on their risk tolerance and trading style. Using appropriate stoploss orders provides valuable protection for traders and investors managing positions in fast-moving, volatile markets.

Why should you use stop-loss?

You should stoploss because using stoploss helps traders limit their potential losses on a trade. It removes the emotion from decisions to exit losing positions. Stoploss orders provide discipline and maintain a predefined exit strategy. They prevent traders from holding on to losing trades in the hope that they will reverse. A stop-loss allows traders to quantify and fix their maximum acceptable loss on a trade. This helps to manage overall risk exposure. With stoploss in place, traders do not need to monitor open positions constantly. The stoploss will automatically trigger the exit if the price moves against the trade. Stoploss helps traders stick to their trading plans and predetermined risk-reward ratios. It prevents impulsive decisions under pressure. Using stoploss helps preserve trading capital and prevents account explosions from large losing trades. It supports long-term survival. Stoplosses allow traders to size positions appropriately and know the maximum loss. This ensures proper position sizing and risk management. Stoploss orders automate the exit process and eliminate emotional decision-making when trades go against you. Stoplosses enforce discipline and positive habits even when traders are tempted to freeze or postpone.

How to place stoploss orders?

For a long position, the stop-loss order is placed below the entry price to limit potential losses if the price falls. For example, you could set a stop-loss at $32 to exit if the price falls below that level if you buy a share for $350. For a short position, the stop-loss is placed above the entry price to limit losses if the price rises. For example, if you short sell a stock at $350, you set a stop-loss order at $371 so that the position is closed if the price trades higher than that threshold. The key is to determine the stop-loss level that is in line with your risk tolerance for that particular trade. Tighter stops limit losses more quickly but are more likely to be triggered by normal price fluctuations. Wider stops provide more room but expose you to greater potential losses if the trade goes against you.

Example of stoploss orders

An example of a stop-loss order is when a trader initiates a long position by buying shares of a stock for SEK 350 per share. To limit potential losses on the trade, the trader places a stop-loss order at 329 SEK per share when entering the long position. This means that when the share price falls to 329 SEK, the stop-loss order will be triggered and a market order to sell the shares at the prevailing market price will be sent. So the shares will be sold automatically, probably at a price slightly below SEK 329 based on the current market liquidity if the price falls to SEK 329. By using this stop-loss order, the trader limits the maximum losses on the long trade to about $10 per share (the entry price of $10 minus the stop-loss trigger of $10). Without a stop-loss in place, the losses could be much greater if the stock continued to fall below $10. The advantage of using a stop-loss order is that it removes emotion from the exit decision. When the price reaches the predefined stop level, the shares are automatically sold without any manual intervention required. This enforces disciplined risk management. A trader shorting shares would use a stop-loss order in the same way but in the opposite direction. For a short position entered at $350, a stop-loss buy order would be added at $371 to limit losses should the stock price rise against the short position.

What are the benefits of using stoploss?

The main advantage of stop-losses is that they provide automated protection against downside risks in a stock by limiting losses. Stop-losses give investors the peace of mind of knowing that their position will be sold when the price drops to a predefined level. This helps limit the damage to a portfolio during market downturns. For short-term traders, stop-losses allow profits to run while quickly exiting losing trades. Stop-losses enforce disciplined selling based on a strategy versus emotional decisions. The predetermined rules force investors to sell underperforming stocks instead of hoping they will recover. Stop-loss also protects against overnight gap declines by selling at the market open. During volatile markets, stop-loss minimizes large swings in portfolio value. For investors who cannot constantly watch the market, stop-losses provide risk management without constant monitoring. Stop-losses allow investors to continue investing knowing they have a safety net if prices fall. Automated selling increases efficiency and removes emotional bias from trading.

What are the restrictions on using stoploss?

The main disadvantage is that a short-term fluctuation in a stock’s price can activate the stop-loss. However, stop-losses help limit potential losses on a position. Stop-losses provide investors with downside protection in the event that a stock falls significantly. The key is to choose a stop-loss percentage that allows a stock to fluctuate on a daily basis while preventing as much downside risk as possible. Stop-losses are automated orders that are triggered when a stock reaches the defined stop-risk level. This ensures that the position will be sold at the stop price or better to limit losses. Stop-losses give investors peace of mind knowing that their downside is limited if the investment thesis turns out to be wrong. Stop-losses require less monitoring than mental stop-loss levels because the orders are automated. Overall, stop-losses bring discipline and risk management to investments. They mitigate emotion-based decision-making when positions move against the investor. Stop-losses help maintain sell discipline even when investors want to maintain losing positions.

What are the most common mistakes to avoid when setting a stop-loss?

The most common mistakes to avoid when setting stop-losses are using broad percentages, arbitrary round numbers, no adjustments, reactive changes, equating stop-loss with a target, ignoring volatility, tight stops on low-priced stocks, no limits on gap-downs, ignoring tax consequences, and no stop-loss at all. Stop-loss should be a reasonable percentage based on volatility. Arbitrary large round numbers leave too much risk. Stops should be proactively adjusted, not reactively chased. Stop-loss is not a profit target. Take into account the average true range when setting the percentage. Tight stops whipsaw low-priced stocks. Consider limits on overnight gap-down risk. Selling sometimes creates tax liabilities. No stop at all leaves unlimited downside. Fine-tuning a stop-loss requires an assessment of risk tolerance, volatility and investment time frame.

Can stop-loss orders be used in all markets?

Yes, stop-loss orders can technically be used in all markets that allow conditional orders, but they are not always effective. Stop-loss orders work best in liquid markets with tighter spreads and continuous trading, such as large exchanges. In illiquid penny stocks or currencies, stop-losses are sometimes not triggered at the intended price. Stop-losses are also less reliable in volatile markets where gap and limit moves lead to execution far from the stop price. Overall, stop-losses are most useful for active traders in liquid markets with tighter spreads and opportunities for active position management. They provide less protection in thinly traded instruments that are subject to gapping and slippage in volatile stock market conditions.

What are some alternatives to using stop-loss orders?

Alternatives to using stop-loss orders include mental stops, lowered averages, timeouts, technical analysis, defined risk options and portfolio diversification. One option is to use a trailing stop order that follows the market price up but does not go down. Mental stops rely on closely monitoring positions and manually selling at a predefined price rather than using automated orders. Lowering the average means buying more shares when the price drops. Time exits simply mean selling after a set period regardless of price action. Technical analysis such as support/resistance or trend lines identify exit points. Options with defined risk limit downside exposure. Diversification reduces the impact of losses in a single position. Ultimately, the choice depends on one’s strategy, risk tolerance and level of active position management.

What is the difference between a stoploss order and a stop-limit order?

The main difference between a stop-loss order and a stop-limit order is that a stop-loss becomes a market order once triggered, while a stop-limit becomes a limit order. A stop-loss order sells the security at the next available market price when the stop trigger is reached. This guarantees execution but not a specific price, which poses risks in fast-moving markets. A stop-limit order sets a price limit after the stop trigger is hit, which limits the maximum execution price and helps reach a profit target. The trade-off is that stop-limits are not guaranteed to execute if the limit price is not reached after triggering, potentially affecting the profit target. Stop-losses provide downside protection but stop-limits allow more control by preventing trades that are significantly below the stop price. While stop-losses unconditionally exit positions, stop-limits allow one to exit based on a predefined limit in volatile markets. The main advantage of stop-limits over stop-losses is to control the execution price once stopped out, in line with the strategy of reaching a profit target. Can stop-losses trigger a buy order? No, a traditional stop-loss order cannot directly trigger a buy order. A stop-loss is a sell order that is triggered when the market price falls to a specified downward price. However, there are ways to use stop-losses to indirectly initiate a buy order. For example, selling a stock at a loss using a stop-loss can free up capital to buy another stock. Some trading platforms also allow combining orders, so a stop-loss sell order can be linked to a buy order on another asset. While it doesn’t directly trigger a buy, a stop-loss sell signal can lead to a manual purchase of undervalued shares or signal a reversal to short sellers. But by itself, a stop-loss is a unilateral order to sell an owned long position, not initiate new long positions. To directly trigger buying, upward stop orders such as buy-stop or stop-limit orders would be required, along with free capital to finance the purchase.
